What I would like to see is if the retirement bonus went back to 100 xp per gen, but the max xp stayed the same. Currently max xp is 1450 at x1 which you would get at gen 15.
If we went back to 100 xp per gen you'd reach it at gen 5.
That way, people would be able to experience the best part of this game more often: trying new builds. As it stands, since all 'looms were nerfed to oblivion it's not like having a lot of them would unbalance the game anyway and there's also only so many you can carry at a time.
